Om IN CARRIAGE-SASE FASTENER AND SUPPORTER.

*HOP-* '.l'h Schedule referred to in these Letters Patent and makingpart of the lame.

Toall whom it may concern:

Be it known that I, WILLIAM STEWART, of the city and county of Hartford,State of Connecticut, have invented a new and improved Method inFastening the vSash of Carriage-Windows; and I do hereby declare thatthe following is a full and exact description thereof, reference beinghad to the accompanying drawings, and letters of reference markedthereon.

The nature of my invention consists in constructing a fastener for thesash of carriage-windows, by which the vsash is supported at the bottomand held up without the use of a frame.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

Figure 1, front view of'sash and door.

Figure 2, back view of sash and door.

Figure 3, top view of sash and door.

Figure 4, section of same.

Figure 5, view of guide and catch.

Figure 6, view of stop.

The door A, I make in the usual form, with a space between its outer andinner sides to allow the sash B to move in freely up and down.

O (D4 are strips of iron, which I term guides; the edges of these guidesprojecting from the sides of the sash B, andsbearing between the side ofthe plate D, whichv is screwed on to the inside of the outside part ofthe door A, and the edge of the plate E that is screwed on to the topofthe inside part.

F F are cams attached on top of pla-te E, and are made to bear againstthe springs G G, that are fastened to the inside of the sash B, near thelower edge. The lower edge of the sash B and guides C C, on the outside,have a. recess c made for the sash B to c ttch on to the top of plate D,when it is drawn up to its required height. This recess is bevelledtoward the lower edge ofthe sash B, to allow the top of the sash toincline inward.

H H are stops to prevent the sash B being drawn up too far, and arescrewed to the inside edges of the space in the door near the top, inwhich the sash slides. The lower ends of the stops are bevelled towardthe outside of the door, that the'projection c on-thel lower end of theguides may catch into them and throw the lower edge of the sash outward.

I is a strap fastened to the lower edge of the sash in the usual way,and by. which the sash can be raisedor lowered.

The operation is as follows:

By taking hold of the strap the sash is raised as high as thc stops willpermit; the spring throws the recess in the sash over the edge of theplate D, which holds the sash from. dropping; the cams are then closedon to the springs, vwhich secures the sash perfectly.

A great advantage is gained by this improvement in supporting the sashat the bottom, by its having no frame or support above the door, and canbe used in a close or open carriage.

When a sash-frame is made on the door, it remains standing where the topwhich is separated in the centre over the door, is let back each wayfront and back, to form an open carriage. When the sash-frame is made inthe sides of the top, the sash would have to be let down before openingthe oor, when the carriage was used as a close one; but in thisimprovement, where the sash is supported at the bottom and the carriageused as a close one, the door can be opened without dropping the sash,and when used as an open one there is no frame standing;

Another advantage is, the guides O O, which are fastened to the edge ofthe sash, prevent the sash being worn when raised or lowered.

I claim the cams F F, vsprings G G, stops H H, guides C C, when arrangedand used for supporting the 4sashof carriage-windows as hereindescribed.
